Introduction

This package was developed as part of Lab Assignment at Linkoping University. This package has function two functions:

1. geocode_response which takes an address as input and returns the lattitude and lognitude associated with that address as a vector. The address is in turn passed to a shiny app connected to google's Geocoding API and shows the address on the map.

2. reverse_geocode_response which takes latitude and longitude as input and returns a complete address. The shiny app shows the address on the map.

It requires the user to provide an API key for google's Geocoding API.

Running the Shiny app (GeoShiny)

# load the necessary packages
library(GeoShiny)

library(shiny)

# run the shiny app from github
runGitHub("GeocodingShiny", "mariatreesa")

knitr::include_graphics("screenshot.png")

Given a latitude and longitude instead of an address the reverse geocode returns the complete address of the location. See the example below.

knitr::include_graphics("Screenshot2.png")

Map views can also be changed from default map view to satellite view.
